T o all who/riftI it may concern:

Be it known that I, Siouiu) Wma, 'a subject of the Crown of Sweden, and a resident Vot' Brooklyn, county of Kings, and State o New York, vhave invented certain new and useful Improvements in Mixing and Measuring Apparatus, of which the following is a speciication, reference being had to the acnipanying drawings, forming a part thereof.

Myl invention relates particularly to mixi undA measuring devices suitable tor proper y proportioning the ingredients employed in thev production of mortar, cement, silicate 15,- bricks, tiles and the like. In this class ot' machinery, it is common to mix and grind together a certain proportion of the ingredients'and thereafter tounix further mate- `rial therewith, but lihave found from practical experience, that while. absolutely preroportionsA of the ingredients I are uniform y fed to the rinding mill, and

A section therethrough.

a uniform proportion of e material is oo nstantly fed to the producties it is discharged from the mill, the discharge from the mill is not uniform and hence the. proper proportion between 4theA material fed from the mill and the material mixed therewith is .not maintained, and the object of my present invention is to provide a means for producing .a uniform proportion of the ingredients at this point, and hence a uniform mixture. I attain this object kby employing a measurin device for the material discharged from t e mill, whereby the material is accurately measured and fed forward in uniform predetermined quantities, the additional material being then added thereto also in uniform predetermined quantities.

same partly in side elevation and partly in vertical section. Fig. 2 is a view in transverse section through a measuring device employed. Fig. 3 is a view in longitudinal For the purpose of simplicity of description, I will describe this apparatus 'asemployed for mixing, measuring and feeding lime and sand in the manufact-ure of mortar, silicatebricks, tiles and the like, but it will, of course, be understood that this intended in no sense as a limitation upon the' use of the apparatus. A

The apparatus'shown comprises a conveyor' 1 for linie, a measuring device 2 for regulutv ing the delivery thereof, a mixer 3 for reoeiit'-A ing the linie, a conveyei measuring device 4 a grinding mill. 5 for receiving the mixed materials. The grinding mill may be of any Patented May 6, 1913-' suitable character, such for instance astlie` device known as a tube mill which is commonly employed for this purpose, the said tube mill containing pebbles which are tumbled in the rotation'ot the mill, and which act upon the sand and linie to grind the same to a line powder, and to further andcompletely mix the two ingredients together. The product from the tube mill is delivered to a vconveyer 6 by which it is conveyed and delivered to a collector and measuring device 7. This device is designed to feed an absolutely uniform quantity of the material to the conveyor S regardless of the variable quantities delivered from the tube mill 5. A simple form 'of such. device is shown in Figs. 2 and 8, the same comprising a cylindrical casing 13, and a rotatable wheel 14 fitted thereto, the said Wheel havin periph-A eral recesses forvpockets 15, and t e upper portion of the casing connecting with the lower end ott the collecting vessel 16 While the lower end thereof discharges to the conveyer 8. 'While a varying amount of the product from the mill 5 may be `received in the collector 16, sometimes more and sometimes less in a given period of time, the pockets or recesses 15 in the wheel 14, will, in the rotation of the wheel, constitute accurate measuring means, whereby the prod' uct fed forward from this point will be so fed with absolute regularity. The conveyer 8 delivers this product to a mixer 9, the said materials are mixed in the mixer 9 and delivei'ed to a wet mixer l0 in which wat/cris.

and from which the product is delivered to a silo and storage vessel l1.

The y various portions of this apparatus are shown somewhat diagrammatically in -the drawings because each of them 1n itself is an old and well known structure and the particular formthereof is immaterial,` The conveying and measuring devices 4' and 10 are shown as simple forms of belt conveyers,`

which being loaded to a uniform degree and runat a uniform rate of speed'carry forA- ward ,a uniform quantity of 'the material. Similarly the collecting vessel and measuring devices 2 and 7 may comprise `any conmechanism for measuring'antl' feeding a uniform quantity-of the 'material received thereby, one simple form an absolutely uniform quantity of material being shown in ,getherL so that' some exceedingly fi'ne `sand is,

mixed with the lime; andto thereafter mix Withthe ground sand and lime theremain` ing 75% of the sand in an unground condi-l tion.' This has `been attempted heretofore, but. as the product of the grinding mill varies very greatly in spite of the fact that inceste is constantly fed thereto, the result has been a constant variation in the relative proportions of the final mixture. W'hat I claim is. l. The combination with a grinding'ii mill,

`a mixer discharging thereinto,'and aplurality of measuring devices for vsupplying predetermined quantities of unlike materials to the mixer, 4of a Icollector', .means for conveyingtlie irregularly discharged product of the grinding mill to the collector, a receiver, means for continuously conveying a uniform amount of the ground mixture from the collector to the receiver and means for simultaneously and continuously conveying a predetermined uniform amount `of anunlike maefial to the collector.
